SPECIFICATION forming part of Letters Patent No. 436,437', dated September 16, 1890. I Application filed December 9, 1889. Serial No. 333,013i (No model.)

To a/ZZ whom it may concern,.-

Be it known that I, EDWIN A. RIDER, a citizen of the United States, and a resident of Racine, county of Racine, and State of Wisconsin, have invented a new and useful Improvement in Hydrocarbon-Burners for Furnaces, te., of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to a burner for furnaces, &c., employing crude petroleum or '7 other volatile oil as a fuel in connection with rangement of the steam or air pipe and oilsupply valve in connection therewith; in the arrangement of the steam or air supply pipes, valves, and nozzle for effecting the vaporization of the oil, and in the arrangement of pipes and valves for cleaning and flushing the oil chambers, ports, and supply pipes, as

'hereinafter fully described and claimed.4

In the accompanying drawings, Figure 1 represents a longitudinal section through my improved burner. Fig. 2 is a plan or end view of the burner-cap or mouth-piece. Fig. 3 represents a section through the T-shaped steam and air connection, taken at right angles to Fig. 1 and showing the steam and `air ports; and Fig. 4 is a plan view of the lever for operating the oil-valve, detached.

A indicates the body or outer shelnl of the burner, made, preferably, cylindrical in form and internally screwthreaded at its ends at a, in its outer end, to receive the cap or mouthpiece B, which is screw-threaded on its outer surface to engage the shell, and outside of said screw-threaded part is provided with an annular flange or collar b, which abuts snugly againstthe end of the shell. Inside of said screw-threaded portion the mouth-piece B is still further reduced in external diameter and Venters and snugly fills the adjoining' end of an adjustable sleeve C. The longitudinal central perforation or bore of the cap or mouthpiece B is made flaring or bell-shaped at both ends, and the outer discharging end has two or more circles of inwardly-projecting points or spurs b and b2, those of the outer circle h2 being set opposite the spaces between i the points b of the inner circle, the object being to effect a thorough mingling of the particles or atoms pf escaping oil and steam or air.

The extreme inner end of the mouth-piece at the end of the inner bell-mouth is cylindrical in form and internally screw-threaded for a short distance to receive a nozzle D engaging said end, and the point or discharging end of which terminates in a bell-mouth chamber b3 at that end of the mouth-piece B, as shown. j Y

The reduced inner end of the mouth-piece surrounded by the end of sleeve C is provided with a series of perforations b4, forming ports opening into the flaring mouth b3, preferably just back of the point of the nozzle D, and through which the oil passes from the chamber A into the mouth or mixingchamber b5, regulated in its flow by the endwise adjustment of the sleeve C, which serves as a valve to open and close the ports or perforations b4 radiating from said chamber.

The outer or lower end of the sleeve C is enlarged and screw-threaded at c to engage the internally-threaded end of the shell A, and on its end projecting beyond the shell has a lever C secured to it through the medium of a ring C2 on the inner end of said lever surrounding said projecting end of the sleeve, and a set-screw c passing through the ring and engaging the sleeve for holding the lever at any desired adjustment.

By operating the lever C the sleeve C ca be adj usted in and out over the adjoining end of the mouth-piece B, and the flow of "oil through the ports h4 regulated, as required, and where several burners are employed the lever C, for operating the sleeves C, can be connected by link-rods to be operated simultaneously and uniformly` The nozzle D is funnel-shaped, and is internally screw-threaded at its larger end to receive a pipe E, which passes ont through the projecting end of the sleeve C. At one point c2 in the internal diameter of said sleeve the bore is reduced to fit the pipe E snugly,` but I not so closely as to prevent the movement of the sleeve relatively to the pipe, and outside of said point c2 the bore is again enlarged to receive a packing f, and outside thereof a stuifing-box F, screwed into the end of the sleeve and snugly surrounding the pipe E.

The outer end of the pipe E is connected through suitable couplings with a cross or T shaped connection G, provided with a needle or puppet valve h, by the adjustmentof which air or steam, either or both, can' be admitted to the pipe E.

The T-shaped connection G is shown in transverse section, Fig. 3, provided on one side with an arm g', through which connection is made with a steam-supply, and on the other side with an arm g2, through which air under pressure may be supplied, both terminating in a central chamber g, connecting with the pipe E through an arm g3, controlled by the Valve h.

The T-connection G has another lateral arm g4, shown arranged in about the same plane with the arms g and g2 and ,communicating at its inner end with the chamber g and connected at its outer end with a perpendicular arm or cross-head G, connected at one end With a pipe I and provided at its other end with a valve-chamber j, communieating with the pipe I and controlled by a valve j similar to that at h.

The pipe I connects at its end opposite that connected with the cross-head Gwith an arm or pipe K, connected with the shell A, and through which and a pipe K', connected therewith, oil is admitted to the chamber A from any suitable supply tank or reservoir.

The couplings for uniting the pipes and valves h and j with the steam and air connections G and G and body of 'the burner maybe of the form indicated in the drawings, or any other or preferred form of couplings may be employed.

The operation of the burner will be readily understood. Oil is admitted through the pipe K to the chamber A', surrounding the sleeve C, and by adjustment of the latter is admitted through ports b4 to the mixing-chamber b3, surrounding the nozzle D., Air under pressure or steam (or both) is admitted to the nozzle D through the pipe E and T-connection .G, controlled by the valve 7i, and the cocks admitting the steam or air into said connection, and is blown out through the nozzle D and mouth-piece or cap B,drawing ut with it and vaporizing the oil in a manner well understood, and a thorough mixing and mingling of the atoms are effected in their passage by the points or spurs b to the outlet and point of combustion, and as a result a steady iiame and a regular supply and thorough combustion of the oil are obtained. By closing the valve h and the cock admitting oil from the tank to the pipe K and chamber A and opening the ports b4 and the valve k,7" steam or air may be forced through the pipes I and K into the chamber A and out through the ports b4 and mouth-piece B for cleaning or iiushing the oil pipes, chambers, and outlets, and by closing the ports b4 and opening the cockcontrolling the supply-pipe K the steam can be forced back through the latter for cleaning said pipe from any gummy or other clogging matter and for warming t-he oil in the tank, as may be required.

Having now described my invention,what I claim as new, and desire to secure by Letters Patent, isy 1. In a hydrocarbon-burner, the cap or mouth-piece provided with a daring or bellshaped mouth having pointed spurs on its daring inside walls arranged in two r more circular rows, with the spurs in one row set opposite the spaces between the spursl of the adjoining row, substantially as described.
